ELECTRIC FAN WITH STAND Filed Jan. 10, 1962' SECTION A -A INVENTOR.

United States Patent 0 3,137,440 I ELECTRIC FAN WITH STAND Peter Schlumbohm, New York, N.Y.; Francis J. Gorman, executor of said Peter Schlumbohm, deceased Filed Jan. 10, 1962, Ser. No. 165,360 1 Claim. (Cl. 230-273) The invention refers to an electric fan, more specifically the invention refers to a centrifugal fan in which the air leaves a cowl in a tangential beam.

The invention is illustrated in FIG. 1 to FIG. 5 of the through which air flows into the impeller 3. On the opposite side, the cowl extends into a casing 4 which envelops the motor of the fan.

The eye 2 has a collar-edge 5, shown best in FIG. 4.

The fan hangs movably and removably on a vertical member or standard 6 mounted on a base 7. The member or standard 6 has at its upper end a hook-like extension 8. The hook comprises a top surface 9, the curvature of which corresponds to the curvature of the collaredge 5.

The fan hangs on this hook which is abovethe center of gravity of the fan. The weight of the motor and of the rest of the fan presses the fan against the member or standard 6, resulting in a stabilized position.

The purpose of the invention is to make this position 35 of the fan changeable, clockwise or counter-clockwise, and thereby to change the angle at which the beam of air, illustrated by three arrows, leaves the cowl at the ejection slot 11.

withthe motor shaft in a horizontal position. If removed from the stand, the fan may rest on the base 10 of the motor housing, operating with the motor shaft in a vertical position.

Of course the invention may also be executed with other fans which are suitable either for vertical or for horizontal motor shaft operation, and the invention is not even limited to centrifugal fans.

Having now described the nature ofmy invention by way of example and shown thetmanner in which it may be performed,

I claim as my invention:

A fan comprising a hollow body, an impeller rotatably mounted in said fan body, drive means connected to rotate said impeller, said body having an air inlet part adjacent the axis of rotation of said impeller and an air outlet part at a peripheral portion of said body, said body including an'arced portion concentric with said impeller axis, and means, for supporting and adjustably rotating said body about said impeller axis of rotation to direct the delivery of air from said fan, said supporting means including a supporting stand having a vertically positioned member, a laterally projected hooked portion integral with said vertical member and adapted to receive said arced portion of said body to detachably support the latter at a point above the center of gravity of'said fan, a portion of said fan body below said point being engageable with said vertical member to hold the axis of rotation of said impeller in a substantially horizontal plane, said fan body being angularly adjustable about the axis of rotation of said impeller by varying the contact point of said hooked portion of said support means along said arced portion of said fan body.
